How to Retrieve the Latest Excel File using Python in Tkinter

What will you learn?

This tutorial will guide you on using Python and Tkinter to select and display the most recent Excel file.

Introduction to the Problem and Solution

In this tutorial, we aim to develop a user-friendly interface with Tkinter that allows users to choose and view the latest Excel file. By leveraging Python libraries such as os for file operations and tkinter.filedialog for file selection, we can create a seamless solution for accessing Excel files within our application.


import os
from tkinter import Tk, filedialog

# Create the main application window
root = Tk()
root.withdraw()  # Hide the main window

# Ask user to select the latest excel file
file_path = filedialog.askopenfilename(title="Select the latest Excel file", 
                                       filetypes=(("Excel files", "*.xlsx"), ("all files", "*.*")))

# Display selected excel file path

  • Import necessary libraries like os for OS interaction and tkinter.filedialog for dialog boxes.
  • Use Tk() method to create a hidden main window.
  • Prompt user to choose an Excel file with filedialog.askopenfilename, specifying filters for only Excel files.
  • Print out the selected excel file path.
  1. How does root.withdraw() work in tkinter?

  2. The function hides the main tkinter window created by Tk(), useful when you don’t want an empty GUI window displayed.

  3. Can I customize tkinter dialog boxes appearance?

  4. Yes, modify attributes like title, initial directory, custom filters while creating dialog boxes using tkinter methods.

  5. How do I handle exceptions if no excel file is selected by the user?

  6. Check if ‘file_path’ variable contains a valid path after calling askopenfilename. An empty string means no selection was made.

  7. Is it possible to filter multiple types of files through tkinter dialogs?

  8. Specify multiple tuples inside ‘filetypes’ parameter with desired extensions separated by commas.

  9. What happens if I close or cancel out of dialog box without selecting any files?

  10. askopenfilename returns an empty string if no selection is made. Check if ‘file_path’ is not empty before proceeding further.


By combining Python’s capabilities with Tkinter, we can build interactive applications that seamlessly interact with external resources like Excel files. Following these steps ensures a robust user experience within our applications.
